The displacement of a particle of mass 2 g executing simple harmonic motion is x=8 (50 t+ 12 ) m , where t is time in second. The maximum kinetic energy of the particle is

Options

  1. A160 J
  2. B80 J
  3. C40 J
  4. D20 J

Correct answer

A. 160 J

Step-by-step solution

m =2 ~g , x =8 (50 t + 12 ) m aligned & V _ = A =8 50=400 ~m / s & ( K E )_ = 1 2 mv _ ^2= 1 2 2 10⁻³ 400 400 & =160 ~J aligned
